Description
Technical field
The utility model relates to the accessory on a kind of Sewing machines, is specifically a kind of edge covering mechanism of sewing machine.
Background technology
The edge covering mechanism of sewing machine of prior art comprises needle plate and flat cylinder, and flat cylinder is directly fixed on needle plate, and needle plate is then fixed by screws on the table top of Sewing machines.Generally, when mounted, flat cylinder is corresponding with the stitch of Sewing machines, enables stitch make cloth in flat cylinder.But the time one is long, and the relative position of flat cylinder and Sewing machines can produce skew unavoidably, make flat cylinder cannot be corresponding with the stitch of Sewing machines, cause sewing generation substandard products.In order to make flat cylinder corresponding with the stitch of Sewing machines, usually needing the screw turned on needle plate, screw of screwing on again after whole needle plate is slightly adjusted, so realizing the adjustment to flat cylinder and Sewing machines stitch relative position.But this adjustment mode operates inconvenient completely, takes time and effort, and the effect of adjustment is not satisfactory.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the relative position of a kind of flat cylinder and Sewing machines stitch easy to adjust, the edge covering mechanism of sewing machine that Adjustment effect is good.
To achieve these goals, the technical solution of the utility model is as follows: a kind of edge covering mechanism of sewing machine, comprise needle plate and flat cylinder, also comprise removable insole pieces, removable insole pieces is slidably disposed on needle plate, flat cylinder is fixed in removable insole pieces, removable insole pieces is provided with for driving removable insole pieces on needle plate along the rocking bar entering cloth direction and reciprocatingly slide, the inner of rocking bar is articulated in removable insole pieces by pivot joint screw, pivot joint screw runs through removable insole pieces and needle plate, the edge of the inner of rocking bar is provided with driving fixture block, removable insole pieces offers the drive hole supplying the mounting hole of pivot joint screw activity and match with driving fixture block, mounting hole is connected with drive hole, pivot joint screw is mobilizable to be arranged in mounting hole, fixture block is driven to be fastened in drive hole.
After adopting technique scheme, the utility model compared with prior art, have the following advantages: the utility model edge covering mechanism of sewing machine drives removable insole pieces to slide on needle plate by rocking bar, thus drive flat cylinder movable on needle plate, realize the adjustment of the relative position to flat cylinder and Sewing machines stitch, structure is simple, and easy to operate, Adjustment effect is good.
As improvement, the fabric input mouth place of described flat cylinder is provided with S shape entering cloth rack.What S shape entering cloth rack can make that cloth can be more smooth-going imports in flat cylinder.
As improvement, the curved structure of shaft of described rocking bar.The hand-type when shaft of arcuate structure is just in time held with people matches, more laborsaving when making to operate rocking bar, humanization designing.
Accompanying drawing explanation
Fig. 1 is the detonation configuration intention of the utility model edge covering mechanism of sewing machine.
Fig. 2 is the detonation configuration intention of another angle of the utility model edge covering mechanism of sewing machine.
Fig. 3 is the structural representation after the utility model edge covering mechanism of sewing machine has assembled.
Shown in figure: 1, needle plate 2, flat cylinder 3, removable insole pieces 4, rocking bar 5, driving fixture block 6, mounting hole 7, drive hole 8, pivot joint screw 9, S shape entering cloth rack 10, riser.
Detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1 to Figure 3: a kind of edge covering mechanism of sewing machine, needle plate 1 and flat cylinder 2 is comprised.The utility model edge covering mechanism of sewing machine also comprises removable insole pieces 3, and removable insole pieces 3 is slidably disposed on needle plate 1.Flat cylinder 2 is fixed in removable insole pieces 3.Removable insole pieces 3 is provided with for driving removable insole pieces 3 on needle plate 1 along the rocking bar 4 entering cloth direction and reciprocatingly slide.The inner of rocking bar 4 is articulated in removable insole pieces 3 by pivot joint screw 8.Pivot joint screw 8 runs through removable insole pieces 3 and needle plate 1.The edge of the inner of rocking bar 4 is provided with and drives fixture block 5.Removable insole pieces 3 offers the drive hole 7 supplying the mounting hole 6 of pivot joint screw 8 activity and match with driving fixture block 5, mounting hole 6 is connected with drive hole 7.Pivot joint screw 8 is mobilizable to be arranged in mounting hole 6, drives fixture block 5 to be fastened in drive hole 7.
In the present embodiment, the fabric input mouth place of flat cylinder 2 is provided with S shape entering cloth rack 9.What S shape entering cloth rack 9 can make that cloth can be more smooth-going imports in flat cylinder 2.
In the present embodiment, the curved structure of shaft of rocking bar 4.The hand-type when shaft of arcuate structure is just in time held with people matches, more laborsaving when making to operate rocking bar 4, humanization designing.
In addition, in the present embodiment, drive hole 7 is connected with the middle part of mounting hole 6, forms a T-shaped hole with mounting hole 6.Design like this, when driving fixture block 5 to drive removable insole pieces 3 to slide, can guarantee that pivot joint screw 8 is movable swimmingly in mounting hole, ensureing that pivot joint screw 8 can not block in mounting hole 6, reasonable in design.One lateral edges of removable insole pieces 3 extends upward a riser 10, and flat cylinder 2 is fixed on riser 10, realizes being synchronized with the movement with removable insole pieces 3 with this.
Utility model works principle: when shaking the outer end of rocking bar 4, the inner of rocking bar 4 is rotated around pivot joint screw 8, the driving fixture block 5 be now stuck in drive hole 7 can drive removable insole pieces 3 to slide, the screw rod of the screw of pivot joint simultaneously 8 is movable along entering cloth direction in mounting hole 6, realizes the adjustment to removable insole pieces 3 position with this.
The utility model edge covering mechanism of sewing machine drives removable insole pieces 3 to slide on needle plate 1 by rocking bar 4, thus drives flat cylinder 2 movable on needle plate 1, and realize the adjustment of the relative position to flat cylinder 2 and Sewing machines stitch, structure is simple, and easy to operate, Adjustment effect is good.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its scope protected according to right.
